1031 Exchange Rules in Connecticut

Last reviewed: June 2026. State rules change. Verify current forms before closing.

What Is Different in Connecticut

Connecticut pairs a high income tax rate — 6.99% at the top — with surprisingly simple exchange mechanics: no nonresident withholding at closing and no exemption forms. The item that catches sellers off guard is the state’s real estate conveyance tax, which applies to the transfer itself, 1031 exchange or not.

Does Connecticut Conform to IRC Section 1031?

Yes. Connecticut follows the federal like-kind exchange rules for real property. A 1031 exchange is an IRS-approved way to sell investment property and buy replacement property without paying tax on the gain right away. If your exchange qualifies for federal deferral, Connecticut defers its income tax too. New to exchanges? Start with our 1031 exchange guide.

Your replacement property can be in any state, and Connecticut has no claw-back or annual tracking of deferred gain afterward.

Connecticut Tax Rate on Real Estate Gains

Connecticut’s top income tax rate is 6.99% for 2026. On a $500,000 gain, that can mean up to roughly $34,950 of state tax in addition to the federal bill. A qualifying exchange may defer all of the income tax.

No Withholding at Closing

Connecticut imposes no real estate closing withholding on nonresident sellers. There is no exemption certificate to request, no affidavit to sign, and no payment held back at the closing table.

The federal mechanics still govern the exchange itself: a qualified intermediary must hold your sale proceeds, and the 45-day and 180-day deadlines apply. A qualified intermediary is the independent party that holds your sale proceeds during an exchange. WealthBuilder 1031 handles exchanges in Connecticut and all 50 states.

The Conveyance Tax Is Separate

Connecticut’s real estate conveyance tax applies to the deed transfer regardless of whether your gain is deferred under Section 1031 — it is a transfer tax, not an income tax, and it applies to all sellers. An exchange defers income tax; it does not remove conveyance tax. Budget for it on the sale, and on the replacement purchase if that property is also in Connecticut.

Federal Taxes Still Apply

A Connecticut exchange defers two layers: federal and state. Here is what a taxable sale looks like without an exchange, using round numbers.

Example: $1,000,000 sale of a Connecticut rental. Original purchase $600,000, with $100,000 of depreciation taken, so the adjusted basis is $500,000 and the total gain is $500,000.

Figures are illustrative and rounded. Your rates depend on income, filing status, and basis. A qualifying 1031 exchange may defer the entire amount. Run your own numbers with our 1031 exchange calculators, then confirm them with your tax advisor.

Risks and Things That Go Wrong in Connecticut Exchanges

• Expecting the exchange to erase the conveyance tax. The conveyance tax applies to the transfer itself, independent of income-tax deferral.
• Assuming no withholding means no state tax. Connecticut taxes recognized gain on your return; closing without withholding is a convenience, not an exemption.
• Boot surprises. Cash taken at closing or mortgage relief not offset with new debt or additional cash becomes recognized gain — taxable federally and in Connecticut now, not later.
• Failed deadlines. The federal 45-day identification and 180-day completion rules apply with no state extensions. See the IRS rules for 1031 exchanges.
• Deferral is not elimination. The IRS and Connecticut will tax the deferred gain when you eventually cash out. Plan the exit, not just the exchange.

Connecticut 1031 Exchange FAQs

Does Connecticut withhold tax when I sell investment property?
No. Connecticut has no nonresident real estate withholding at closing and no exemption form to file.

Can I exchange my Connecticut property for property in another state?
Yes. Replacement property can be anywhere in the U.S., and Connecticut does not claw back or track the deferred gain afterward.

Do I still need a qualified intermediary in Connecticut?
Yes. The QI requirement is federal — your sale proceeds must be held by an independent intermediary, not by you, in every state.

Does Connecticut track my deferred gain after the exchange?
No. Connecticut has no claw-back rule and no annual reporting tied to deferred exchange gain.

Does a 1031 exchange avoid Connecticut’s conveyance tax?
No. The conveyance tax applies to the deed transfer regardless of income-tax deferral. The exchange defers income tax only.
